The invention relates to knitting-machines, and particularly to thosewhich produce a fabric comprising a' succession of articles adapted tobe separated.

One of the objects of the invention is to provide improved means for theformation of a lock-stitch, and, as the machine is organized,particularly for forming a locke stitch as the connecting-web betweensuccessive articles, so that when vseparated each may have a selvageedge.

A further object is to provide -improved means for forming a halfcardigan-stitch and for changing from this to other forms of stitches.

Further minor objects will be in the descri )tion of the machine.

' The inteiilocked stitches are formed by what is known in the art asrackin lt consists in alternately shifting one oft Ie nee- (lle-platesback and forth longitudinally with developed reference to the otherbetween several suc-- ceedingforward and return strokes of thecamcarriages. lIn this way each of the needles of one set is advanced toreceive the yarn alternately into each of two adjacent interspaces ofthe other set of needles. ln the machine to be described this rackingmovement is produced during the formation of several rows of knitting inthe formation of the body of each garment, as well as at the point wherethe articles are to be separated, in order to give a more finishedappearance to the fabric.

The invention. consists in the construction and arrangement of parts tobe hereinafter described, and which are illustrated in the accompan yingdrawings, in which-` Figure 1. isa side elevation of the machine.

In the drawings there is shown a straight type of knitting-machinehaving vtwo copernot included in the invention are shown conventionally,and others which have no bearing at all upon the operation of the partsinentirely.

The machine is carried by a .frame com- -prising uprights, 51,.and 52,the ioorplate 53, lower side rails 54 55, and upper side rails 56 and57. Cam-carriages are shown at ,58 and 59 and a frame for a yarncarir at60, these parte being adapted to re. ciprocate over the needle-plates 63and 64. For this purpose rods 61 and 62 are joined to the cani-carriagesand are 'united by a crosshead 65, which travels in ways 66, formed inthel upper side rails 57. This cross-head is driven by a mechanism whichin its simplest formmay consist cfa swinging lever 67, pivoted to thecross-head and fulcrumed at the base of the machine. As the cross-head65 moves in a straight line,- it is important that the fulcruin for thelever 67 be movable, and to this end a link 68 is pivoted to the lowerend of the lever and to a floor-hanger 69, secured to the 'floor-plate53. The lever 67 is i actuated by means of a pitman 70, driven by l acrank 7l on a shaft 72, journaled in the i lower side rails 54 55.

At theback of the machine a large gear is ating banks of needles;y Someof the partsv volved in the invention have been omitted tionalview onthe line 13 13 of F ig.,10. Fig.

mounted-upon this shaft, which -meshes`with a pinion 74 upon acounter-shaft 75, which provided with the usual belt-pulleys 76,. The

-counter-shaft 75 is extended through to the front of the machine andprovided with a hand-wheel 77, which finds coiwenicn t use in setting upthe machine.

The needle-plates 63 and (54 are provided with the usual transverseslots or ner-uile-` Ways 78, in which are fitted needles 79 of usualforni, each'having a cani-engaging lug 80 extending upwardly into thepath of the cam-carriage and resting upon. a needle-supporter 81 whichis provided with a downwardly-projecting finger 82, riding upon apattern-cylinder S3, having elevated and deressed portions, as 84, forraising and lowering the needle into and out 'of action Each of theearn-carriages 58 and 59 is )rovided with an advancing cani-plate 85,which has double-inclined cani-surfaces 86 and. S7 for engaging theneedle-lugs when moving in either direction. There are also provided foreach carriage two retracting-cams 88 and 89, which, as their positiondetermines the tension of the knitting, are niovably attached to thecam-carriages by means of pins 90, moving in slots 91 in the floor ofthe carriage. Each of these retraeting-eams is slotted as usual, asshown at 92, this slot receiving a wrist-pin 93 upon a crank-disk 94 atthe. base of an upright shaft 95, journaled in the frame ofthe carriage.This shaft is provided at its upper end with a worm-wheel 96, meshingwith a worm 97, journaled in ya bracket-arm 98, rising from. the back ofthe carriage and "running upon a square shaft 99, extending over theneedle-plate for its entire length and journaled in brackets 101, risingfrom the frame of the machine.

The square shafts 99 and the pattern-cylinder 83 are intermittentlydriven, as may be desired to produce the required pattern. in thefabric, by means of a pattern mechanism carried by the 'end vupright 50of the frame of the machine. The pattern-cylinder 83 is extended ineither direction by. shaft-sections 102 and 103, which are journaled,respectively, in the end plate 50'and in. a hanger 104, depending fromtheinner end of the needle-plate, the cylinder being free to rotateindependently of the shalt-section 103,' but movable longitudinallytlmrewith.

ApaWl-arin .105, Fig'. 16, carrying a springlpawl 106, is rotatablymounted on the outer end of the' shaft 102 and col'ierates with a-ratcliet-wheel 107, fixed to such shaft. A

dog 108 is pivoted to the fra-nie of the inachine and engages the teethol' the ratchetwl'ieel 107 to prevents its turning in the oppositedirection. A cani-plate 109 is provided for swinging the paul-arms so asto advance the patterii-cylinders 8S. This cam-plate is mounted upon ahollow sleeve 111, supportl ed-by a stud 112, securely fixed. in theframe of the machine. A spring 110 reacts between the pawl-arins 105.130insure their engagement with the face of the cam-plate 109.

The hollow sleeve 111 and its cam-plate 109 are driven from the maindriving-shaft of the machine. As the mechanism for transmitting themotion forms no part of the present invention, it is conventionallyshown to be as follows: A shaft 113 extends along the machine from the uright 51 and projects through the face of tie end plate 50. This shaftis driven from the shaft 72 by means of a pinion 115, which. through themedium of an idler 116 drives a gear 117 keyed to the hollow shaft 1.11.

Each of thesqua e shafts 99 carries on its forward end a pinion 118,which meshes with a gear-rack 119, extending across the end of themachine and supported by guides projecting from the brackets 100. Thisgearrack is joined by a link 120 to a bell-crank lever 121, pivoted tothe frame of the .machine at 122 and operatively connected by atension-rod 123 to a swinging lever 124. From the forward end of thislever a cam-engaging linger 126 projects into the path of cani-blocks127, secured vto the face of a pattern-ring 12S andadapted. to swing thelever Le and reciprocate the gear-rack 119 when they come intoengagement with the finger 126. A spring reacts between the frame of themachine and the lever to return it to its normal position when itsforward end becomes disengaged from the cam-block.

The pattern-ring 128A is driven in the following mairner: 'A beveledgear. 129 is formed upon the inner face of the gear 117, carried by thehollow sleeve 111, and meshes with a gear 130, carried by a verticalshaft 131, running in suitable boxes secured to the inner face of theend plate 50 and carrying at itsy lower end a worin 132, actuating aworinwheel 133, mounted upon the inner end of a short horizontal shaft134, journaled in and extending through. the plate 50. A pinion issecured'to the outer end of this shaft surface of the pattern-ring 128.plate 1.36, recessed to receive the pinion 135 and having a smooth riln,forms a bearing for the apexes of the gear-teeth of the patternring 128.This crescent-plate is secured by a bolt 13S to a bar 137, mounted onthe end plate 50 :1nd having a T-slot for receiving the head of the bolt1.38. The crescent-plate is provided with a shoulder 139, between whichpattern-ring 12S runs.

For knitting garments of different sizes it necessary to providepattern-rings, as 128, of greater or iess circumference, and thisconstruction permits the interchanging of rings skew-gears 114' andcarries on its forward end` IOO and engages gear-teeth formed on theinner A crescentand a large washer 14.0 on'the bolt 138 the seance .Foreach patterncrescent-plate 136 of various dimensions. ring there 1sprovided a are spaced apart so that j. cation of the shaft causes thedesired tion by a key 142a 'dles the bar 137 at any such point as willbe found necessary for the proper engagement of the teeth of the pinion135 and the internal gear of the pattern-rin 'As so far described themachine presents no new features, the automatic means for shiftingthe'retracting-cams of the cam-carriages for changing the tension of theknitting and the nieansfor rotating the patterncylinder 83 being shownand described in Letters Patent No. 670,159, granted to William K.Millholla'nd and Ulysses G. Lee.

As previously described, a lock-stitch is formed by reciprocating one ofthe needleplates longitudinally a distance equal to the spacing of theneedles, so that each of its needles is advanced alternately on oppositesides of the coperating needle of the other bank.- To this end oneof theplates, as 63, is mounted in longitudinal Iways 141, Fig. 3, formed .inthe upper side rail 56 ofthe frame of the machine.

A shaft 142 is journaled within the shaftsection 102, which is madetubular for its accommodation, and projects loosely through thepattern-cylinder 83 and enters the shaftsection 103. It is so joined tothe shaftsccas to permit independent longitudinal reciprocation of thelatter. but insure its rotating` with the shaft. There is mounted uponthe extreme end of the lastnamed shaft-section a drum 145, carrying' twoannular series and relatively staggered sets of radially-projectingstuds 146. A cam-block 147, secured, by means of suitable bolts, as 148,to a bracket-arm 150, attached to the frame of the machine, cooperateswith the studs 146. This cam is substantially diamond-shaped, having atboth ends oppositely-inclined faces 151 152, and the cani is, sopositioned as to engage the inner faces of both series of studs. Thesetwo sets of studs members of each series are constantly in contact withthe opposite faces of the cam, whereby the shaft 103 is caused toreciprocate longitudinally as it rotates.

The width of the cam 147 determines, of course, the extent of thisreeiprocation and is shown as being suilicient to move Vthe shaft adistance equal to the spacing of the nee- The shaft is provided withshoulders 143 1,44, engaging, respectively, the opposite ends of thebracket 104 within which the shalt is journaled, whereby the reciprorecirocation of the needle-bed63, to which the bracket 104 is attached.

F or convenience in assembling the parts the shaft 103 is comprised oftwo sections united by a coupling member 103, having oppositely-directedthreaded shanks which screw into the two parts of the shaft, the body ofthis coupling member constituting the shoulder 143.

It being essential that the 83 shall rotate independent section 103 butreci rocate longitudinaliv therewith, in order 't at itsrelation to theneedles be not disturbed in making the lockattcrn-cylinder f of theshaftstitch, the trunk of the pattern-cylinder isv shown as beingprovided with a radiallyrojecting iiange 83, which is seated within achamhered head 103 at the inner end of the shaft 103, and an annularcap.83, screwed upon the head 103b, overhangs the iiange 83". Therotation of the shaft 142 is controlled by the pattern-ring 128 by thefollowing described means: A u spring-pawl 154, swings upon the outerend of the shaft 142 ratchet-wheel 149, secured to the shaft.

portion of the ratchet-wheel is cut away,

as indicated at 155, Fig. 3, to receive the end of the hollow shaft 102.n annular groove ,156, Fig. 3, is cut in the shaft 102 adjacent its endand loosely receives the oint of a screw 157, set in the ratchet-whee149, so as to maintain a uniform relation of the parts l when thepattern-cylinder 83 is reciprocated i upon the shaft 142.

The free end of the pawl-arm rides upon the periphery of a cani-plate158, Figs. 3 and 17, which is loosely 4mounted on the constantly-drivensleeve 111, but may be made to rotate with it in the following manner: Al disk 159 is fixed to the sleeve 111 adjacent to the cam-plate, and isprovided with a plurality of recesses 161, Figs. 10, 15, intended j toreceive a pin 160, reaching through the i cam-plate 153 and forcedinwardly by means of a spring 162, extending over the end of the shaftand Asecured to a plate 163, also loosely mounted on the shaft andhaving a segmental recess through which the pin projects. his plate 163carries a wedge 164, Fig. 11, the point of which. may pass under theoverturned head of the pin 160 and also radiallyprojecting studs 165,which are intermittently engaged by a stop-arm 166 toprevent therotation of the plate. This stop-arm is pivoted to the frame of themachine at 167, Aand its forward end rides on the periphery of thepattern-ring 12S land is held thereto by a spring 166. v

Normally the free end of the arm projects into the path ofthe lugs 165,'but the patternl ring is provided with elevated portions 168 160, Figs.2, 12, which swing it out of their path. When rotation of the plate 163,l is prevented by contact of the stop-arm with th'c ,pins 165, theforward movement of the cani-plate 153 carries the head of the' pin 16()up the inclined face of the wedge 164, so as to withdraw its inner endfrom one of the repawl-arm 153, having a and cooperates with a IOOWedge-block and insert thebpoint ofthe pin thro gh a slotted apf- 160into one of the recesses o1' the disk 159,

and so cause the cam-plate 158 to rotate With the sleeve 111. v

By giving the periphery ol the patternring 12S the necessaryconformation the vracking may be produced at any desired point in theformation oi the fabric and continued during as many rows of knitting asmay be required. In the machine as illustrated elevated portions 168 and169 are formed on the pattern-ring to swing the stop-arm 166, so as toproduce the racking during several successive strokes of the niachinejust previous to the raisinv' of the swinging lever 124 and just afterallowing it tofall.

The rotation ol the cani-plate 158, which swings the pawl-arin 153 toproduce the racking of the needle-plate when in operation, bears adeiinite relation to that el the driving-shaft 72, the two are thenpositively connected by as system ot hearing, including the spur-wheel117,l mounted on the sleeve 11.1, the idler 116, the pinion 115, and theskew-gears 114. These gears are so proportioned that the shifting o1Ethe needleplate always occurs at the end of a stroke ol.t thecams-carriage over the plate. Furthermore, te insure an instantaneousshitting o1' the needle-plate While the cam-carriage is at the end ofits stroke the 'forward cam-faces of the cam-plate 15S have a sharpincline or Pitch, whereby the outward or e'll'ec-tive stroke of' thepaWl-arm 153 is exceedingly rapid. 1

As before mentioned, provision is made `for knitting a halt-cardiganstitch duringr thel formation. of a part el' each articleI and forchanging to another lorm ol stitch from that used m the inaJor part ol'the garment. lVhen.

knitting the half-cardigan stitch, the needles of' one bank, preferablythe front bank, are only partially advancedby the cams of thecani-carriage as it moves in one direction, but are completely advancedby the same cams moving in the opposite direction. To

this end the advancing cani-plate of one oi the cam-carriages, as 58, ismovably attached to the lieorof the carriage, having pins 17()ln'olieeling through slots 171 in the iloorplate, and third pin 17 2extending up ture in the ody ol" the to a point in line with the warntWheels 96. This cam-plate is maintained in its advanced position bynieans of a small coil-spring 173; but the incline of the slots 171being normal to the ca1n-face86 the needle-lugs 80, bearing against this'face as the carriage moves forward, depress the caniplate to a positionindicated by dotted lines in liig. 6 and ride over its up er edge 85aWithout being completely a vanced. As soon, however, as all of theneedle-lugs have passed over the cam-plate it is advanced by the actionof the spring 173, and as the slots 1.71 are parallel to the cam-face 87the camplate is not depressed during the return stroke. By thisarrangement ol the advancing-cam the needles of one side of the machineare advanced only far enough during the forward stroke to receive a newstrand of yarn without passin the loops already held in their hooks overtghe latches. No stitches are therefore cast oil when the needles aredepressed by theL retracting-cam 8S, but tWo strands of yarn are held inthe hooks to be `stroke of the carriage.

When the retracting-cains 88 and 8'9 are shifted to the forward osition(indicated by dotted lines in Fig. 6) tor increasing them tension of thestitches incident to the formation ot the more closely knitted partsofthe garment, a contacting piece 1711, Fig. 9, carried by an arm 175,projecting from one of the worm-Wheels 96, is brought into the path ofthe pin 17 2 to prevent the depression et the advancing-cam plate-S5 bythe pressure of the needle-lugs against its forward tace. lVith'the camsin this position the needles ci' both sides of the machine receive asingle strand of yarn eac-h time they are advanced and cast ell a singlestitch each time they are retracted. This relative arrangement of themechanism for shifting the retracting-canis and that for lockingthe'advancing-cam is of course not essential to the operation of either.

The stop 174 is adjustably secured to the arm 175 by means of set-screws176, passing through slots 177 in the arm, so that it may be set to comein contact with the pin 172 when the worin-wheel 96 is in the positioncorres )ending tothe setting of the retractingcams tor the desiredtension of knitting. l

The operation of the machine as illustrated is as follows: While thecam-engaging linger 126 et the swinging lever 124 rides upon either ofthe cam-blocks 127, the lretractingcams S8 S9 are yshifted to thedotted-line position ofFig. 6, and the stop 174 is thrown into the pathol" the pin 172 to prevent the retraction of the cam S6. A fabric is new`formed composed of closely-knitted stitches, and which may be the cuillportion o l" a garment. The stitch may be ol" any form, in which all theneedles in action cast oil' a sin-- gle loop el" yarn at each stroke ofthe earncarriege, the partirailarjk ariety ol`Y stitch be- IOO IOC

swings the lever 124, so as to eeaocs rack 119. This by rotating theshafts 99 and 100 changes the setting of the parts of thecam-carriz'iges to that shown in full lines in the various figures ofthe 'drawings' and removes the stop 17 4.- from the path of the pin 112.The earns now operate uplon the needies and are acted on by them in sucha way as to produce the half-cardigan stitch previously4 described and`a more openI fabric. During the formation of this part of the garment,and preferably immediately after the change is made to this form ofstitch, the stop-arm 166 is engaged by one of the elevations 168 of theout of the path of the pins 165. This causes the racking movement tobegin, and it Icontinues during the formation of severalrows of knittingor -until the elevated portion y168 passes out from under the point ofthe stop-arm 166, and this arm i'nto the path ofthe the s ring 166". T elock-stitch produced by t 's rackin movement forms a more closelyknitted abric than the half-cardigan stitch reduced without the rackinand is a suitab e 'gradation between this an the taut is again swungstitches of the cuff portion of the garment.

After the elevation 168 passes out of en agement with the sto -arm 166and until t is is reached by one ol the elevations 11,69 of thepattern-ring a loosely-knitted fs; fc ccmnosed of half-cardigan stitchesis produced. cveral other rows of interlocked stitches are formed whenthe stop-arm 166 is swung out of the path of the pins 165 by theelevated portion 169 of the pattern-ring, and in the machine organized,as shown, immediately after this elevated portion passes beyond thepoint of the stop-arm the lever 124 is swging y the cam-block 127to'change the setting of the parts of the cam-carriages for againforming the more closely knitted stitch.

It Will be understood from the foregoing that the fabric produced b themachine comprises aplurality of close y-knitted portions and interveninportions of more open knitting ,j oined to t e closely-knitted portionsat either end b connecting-webs of interlocked stitches. T e fabric maybe divided as desired -by cuttin through an of such ,webs, whichprefcrab y are not ess than three courses of stitches in length, wherebyif the cut is made through an intermediate one of such courses a sclvageed fe at one side and a series of lock-stitches at the other side of theyshift the gearpattern-ring 128 and swung ins 165 by the action ofcrank-shaft.

cut results. It has been found convenient to separate the fabric bycutting through all of those connecting-webs of interlocked Y stitchesis of course determined by the conformation ofthe pattern-wheel, whichmay be changed as desired.

Rotative connection is established between thc shaft-section 102 and thepatterncylinder 83 by pins12, projecting from a flange 1132* on the endof the shaft-section into suitable sockets in the end of the trunk ofthe pattern-cylinder. When the cylinder 83 isjlongitudinallyreciprocated, there is a movement of the cylinder-trunk on the pins; butthe reciprocation of the cylinder is not sufficient to cause these partsto be separated. v 4

In the preferred construction of the machine the cam-plate 158 takes theform of a star having three points and is so driven as to swing thepaWl-arm 153 and shift the needie-plate 63 between each complete cycle(advance and return stroke) of the cam-carriages. The pattern of thcknitting may be changed by substituting for this cam one of differentform which will shift the needleplate more or less frequently. In Fig.21 is shown such a cam 17 8, having six points and which may be employedto shift the needleplate at the end of cach stroke of the carriages.When the needle-plate is so shifted, a fabric of interlocked stitches isproduced, the form of the stitches having a peculiar ornamental effect.
